Patented July 7, 1942 UNITED STATES OFFICE 2,289,284, INTERCHANGEABLEARROWHEAD Tommie B. Chandler, near. Compton, Calif. Application February19, 1940, Serial No. 319,602 3 Claims. (01. are-106.5).

My invention relates to arrowsand the principal object is to provide anarrow that will perm t o s ea b in a remove and. .1 plac d- Th i t n t aa tasev f m i v n n. s tha en n arch comes. a cu tomed o a er a arrowand can shoot same accurately, he may n ver h s u e s m shaft th aplurality of arrowheads that aiford the same balance for the arrow. Thismay be obtained by having the different heads of the same weight (eventhough they vary in shape), or in certain cases the weight may besomewhat difierent, providing the balance, of the arrow is notdisturbed. Thus an archer may obtain the same accuracy and approximatelythe same distance irrespective. of the type or shape of head. However,heavier or lighter arrowheads or tips may be used for special purposes.

Another object is to be able to provide different arrowheads fordifferent types of hunting, or to provide a head merely for targetpractice.

The invention also comprises novel details of construction and novelcombinations and arrangements of parts, which will more fully appear inthe course of the followin description. However, the drawing merelyshows and the following description merely describe an embodiwhich isgiven by way of illustration or example only.

In the drawing, like reference characters designate similar parts in theseveral views.

Figures 9 and 10 show modified forms of shafts in section and modifiedforms of arrowheads in elevation.

Figure 11 is a disassembled view, partly in section, of the form showninFigure 3, taken in the direction of the arrow D.

Figure 12 is a modified form of tip that may be used on the arrow shownin Figure '7.

Referring more in detail to the drawing, the reference number 14designates a wooden shaft of an arrow. The usual feathers and reartended to strike and notched end for the shaft are not shown since theyare well known to those skilled in the art."

The forward end of the shaft I4 is tapered, as shown at '15, and isreceive'd'in the interiorly tapered end I6 of aferrule H. A pin l8fastens the ferrule H on the'tapered end It. The ferrule has a tappedend I9. The ferrule is tapered exteriorly in order to permit a greaterthickness of the shaft at the point C, which is the point of greateststress between the shaft and the ferrule.

The drawing shows several forms of arrowheads, but it is to beunderstood that other forms may also be used. Those shown are by way ofillustration only.

The form of'arrowhead shown in Figures 1 and 2 is for hunting birds;This form comprises a shank 20 which is drilled for reception of aseries of rods 21 that are radially disposed with respect to the axis ofthe shank. A conical orv ointed tip 22 streamlines the front of thearrow; The shank has a threaded stud 23 projecting rearward, forscrewinginto the tapped opening 19, to attach the arrowhead to the shaft I4,through the intermediary of the ferrule [1.

This arrowhead is for shooting birds. The spread of the rods 2! may belikened to a spray ofshot from a shotgun, ince this arrowhead coversaconsiderably wider'area than the mere diameter of the shaft. This pointis primarily instun a bird, whereby it may be'captured.

The rods 2| have a friction-type fit in the shank 20, but are'removable,'in order to replace them when they become broken or bentbeyond repair. The rods 2| are preferably spring steel.

By reason of their comparatively small diameter, they offer very smallresistance to the flight of the'arrow. The streamlined tip 22 of courseaids in cutting down wind resistance and directing the flight of'thearrow.

' Forhunting game, such as deer, etc., a tip 24 having a blade 25 may beused. 'Of coursedifferent sizes of blades may be'used for differentpurposes. As best shown in Figure 11', the tip 24 is slotted, as shownat 26,"and the'blade is inserted in the slot. The blade 25 is. sweatsoldered, or otherwise fastened in the slot 26. Thus when the; blade 25-becomes broken, it may be easily removed by heating the tip 24 andmelting the solder. The blade 25 may of course be made replaceable byother fastening means.

The blade 25 has tail members 21 that extend rearwardly with regard tothe body of the blade. These tail members bear against the side of theferrule I! to reenforce and strengthen the back edges of the blade. Thisarrangement also insures greater accuracy in assembling the blade in theslot 26.

The blade 25 may be assembled in the slot so that it is removablewithout heat, so that if the blade gets stuck in an animal or object,the shaft and tip (without the blade) may be withdrawn.

An arrowhead 28, such as shown in Figure 4, is ordinarily used fortarget practice and other uses. It has a pointed tip 29 and is knurled,as suggested at 30, to facilitate unscrewing the tip as is the head 24of Figures 3 and 11, to faciliitate removal thereof in the event ofdetachment of the blade 25.

The arrowhead 3|, as shown in Figure 5, has a blunt end 32. This headmay be used for hunting rabbits and other game. This head 3| isapproximately the same weight as the target head 28, so that when anarcher becomes accustomed to the target head, he will get the sameaccuracy with the blunt head 3|.

Figure 7 shows a shaft 33 provided with a notch 34 at its rear end, butit will be noticed that this shaft is not feathered, since it is to beused in water for shooting fish. The shaft 33 has a tapered end 35 whichhas a slot 36 at the side of the tapered end 35. A fish arrowhead 31 hasa body 38 slotted at 39 in which swing barbs 4B. The barbs are pivotedon the pin 4| and have shoulders 42 that engage the end of the slot 39,to limit outward movement of the barbs 40. The opposite end 43 of theslot 39 limit the inward movement of the barbs 40, as shown by thedotted lines in Figure '7.

The rear end of the body 38 has a flaring ferrule 44 which receives thetapered end 35 of the shaft 33. The portion 45 of the body 38, which isbetween the slot 33 and ferrule 44, has a bore 46 through which isnormally passed a fish-line 47. A knot 48 at the end of the lineprevents the line from being pulled through the bore 46. A double clovehitch 49 is caught around the shaft 33 and a loose loop 50 connects theclove bitch with the knot 48.

The forward end of the body 38 is tapped, as shown at to receive athreaded stud 52 on the end of a tapered point 53 that carries a blade54. The blade 54 is preferably of substantially the same width as theaggregate width of the barbs when they are in their closed (dotted line)position.

Figure 12 shows a point 55 which may be substituted for the point 53 andits blade 54. The blade 54 is used where it is desired to cut anincision so the barbs 43 may enter the fishs body, such as in the caseof a fish having a tough skin. The pointed tip 55 reduces waterresistance and is sufficient to enter the body of a fish having skinswhose consistency is less tough.

In the use of the fish head, the arrow is shot from a bow with the partssubstantially as shown in Figure 7, but with the barbs in their closedposition. Then when the blade 54 and barbs 40 enter the fish, the barbsswing outward when the archer tends to pull back on the line 47. Thispull on the line draws the shaft 33 out of the tapered ferrule 44, sothat the shaft will not be broken in the subsequent fight of the fish.The head, barbs, blade and point act as a harpoon and by means of suchparts the fish is landed.

In Figure 9 a hollow metal shaft 56 has a threaded thimble 5! insertedin an open end of the shaft. The thimble is interiorly threaded toreceive a threaded stud 58 on the arrowhead 28.

In Figure 10 a solid metallic shaft 59 is tapped at an end 60 to receivea threaded stud 58 on the head 28.

The use of all of the forms of my invention is believed clear since eachof them is shot from a conventional bow in a conventional manner, andthe particular operation and use of each form has been hereinbeforedescribed in connection with the description of each form. It is to beunderstood that other connecting means may be used instead of the screwthreaded connection, by which I provide interchangeability for difierentarrowheads.

While I have illustrated and described what I now regard as thepreferred embodiment of my invention, the construction is, of course,subject to modifications without departing from the spirit and scope ofmy invention. I, therefore, do not wish to restrict myself to theparticular form of construction illustrated and described, but desiredto avail myself of all modifications which may fall within the scope ofthe appended claims.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

1. An arrow comprising a shaft, a ferrule of the same diameter as theshaft fixed at one end around an end portion of the shaft and having athreaded socket beyond the shaft end, a head having a portion of thesame diameter as the shaft and ferrule, abutting the outer end of theferrule and provided with a threaded extension within the threadedsocket of the ferrule, said head having an endwise slotted tip, and ablade seated in the slot of the tip and having tail portions extendingrearwardly along, and against, diametrically opposite points of theferrule.

2. An arrow comprising a shaft, a removable tip having a threadedconnection with the shaft, and a blade relatively fixed on the tip forordinary archery purposes, the blade having tail members extendingrearwardly with respect to the tip and engaging the opposite sides ofthe shaft for reinforcing the blade in its position and substantially toprevent rocking of the blade in opposite directions on the tip.

3. An arrow comprising a shaft, a removable tip having a threadedconnection with the shaft,

the shaft and tip having abutting faces limiting inward screwing of saidthreaded connection, and a blade relatively fixed on the tip forordinary archery purposes, the blade having tail members extendingrearwardly of the said abutting faces and engaging the opposite sides ofthe shaft for reinforcing the blade in its position and substantially toprevent rocking of the blade in opposite directions on the tip.
